IMPROVEMENT In LIGHTNING oonnucrons;

TO ALL WHOM IT MAY CONCERN y Y 18c it known that ire-J. A KISSELL and BLIcKEXsDUFEn, of Chicago, in the county of Cook, and State ofIllinois, have invented certain new and useful improvements in Lightning Conductors; and we do hereby declare that the following ls'a full, clear, and exactdeso'ription thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever-they occur.

To enable others skilled in the art to construct and-use our invention, we will proceed to describe it. Our invention consists in constructing the fiat conductor with ribs at the edges'to give it greater strength,

and revent it from bein torn'or broken and also to render it more ri id. b 7 I a:

Figure 1 is .a side View.

Figures 2, 3, and 4, end views of the same.

In using the. fiat copper rod as a lightning conductor, experience has demonstrated that when made of a thin strip of uniform thickness, in the usual manner, it is liable to be torn or broken at the edges, and'when the edge hasbecome once fractured, it is liable to become soon severed, thereby to destroy its use as a condnctor. To remedy this diificulty-the strip has been strengthened by wiring? the edges, that is, by turning the edges of the strip over a piece of wire, as is usual with tinners. This p'lanyhowever, necessitates a separate operation, adds to the expense, audit is found that the iron wire soonrusts and becomes destroyed. To obviate these difiiculties and provide a rod havingthe requisite strength, without 'an unnecessary increase of the metal, we roll out a strip of thepropcr 'width and thickness to form the rod, and at the same time form on the edges a rib, a, of greater thickness than the body of the red, as shown in thedrawin s. These ribs a are formed a central rib, 6', may be formed at the same time and in the same manner; but this central rib we do not consider of so muchjmportanee as those on the edges, as shown 'in fig. 4. The rod thus constructed is intended to con sist of one continuous fiat strip, and be put up in that condition, withont being twisted or otherwise altered in form, except at the upper end, where that portion which projects above the building-is to be made tubular, in order to give toit the necessary rigidity,.to support itself and the point. The rod is to be attached to the building without the use of insulators, by simply nailing strips crosswise over the rod against the building.

By this method of constructing the conductor, we are enabled to furnish a rod having its edges strengthened without wiring or subjecting it to any additional process or operation.

Having thus described our invention, What we-claim, is- A lightning conductor consisting of a strip of copper, having the ribs it formed solid therewith, as herein shown and described. I 1 Y JACOB A. KISSELL,
